SEE MORE – By reducing nuisance algae growth on glass and in your tank, Nualgi improves water clarity and visibility to reveal more of the tank’s environment and its inhabitants.

FEED LESS – By restoring missing nutrients, Nualgi brings balance to the natural marine food chain from the bottom up by promoting the growth of diatoms and zooplakton – free food for your fish and corals!

CLEAN LESS – Nualgi controls and prevents the growth of nuisance algae as diatoms produced by Nualgi out-compete bad algae for nutrients and increasing dissolved oxygen (DO) levels, improving water quality – fewer water changes!
